DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Avoid if sensitive or allergic to ashwagandha products or any of their ingredients. Dermatitis (allergic skin rash) was reported in three of 42 patients in one ashwagandha trial.

Side Effects and Warnings

There are few reports of adverse effects associated with ashwagandha, although there are scant human trials using ashwagandha, and most do not report the doses or standardization/ preparation used.

Ashwagandha may cause sedation, possible life- threatening respiratory depression, decrease blood pressure and cause abnormal heart rhythms. Ashwagandha may cause diarrhea. Nausea and abdominal pain have also been reported. Theoretically, irritation of mucous and serous membranes may occur, and ashwagandha should be avoided in peptic ulcer disease.

Ashwagandha may lower blood sugar levels, based on limited human research (in patients with type 2 diabetes), and therefore may interact with diabetic medications, although the mechanism is unknown.

Ashwagandha has been reported to possess diuretic properties, and kidney lesions may occur. Ashwagandha may stimulate thyroid function and increase T4 levels, possibly increasing risk of hyperthyroidism. Ashwagandha may also possess androgenic (testosterone- like) properties, based on rat evidence of increased testicular weight and spermatogenesis, as well as decreased serum FSH and testosterone levels.

Ashwagandha may stimulate red and white blood cell production, and increase platelet count, although there is limited study in these areas and mechanism is unknown. Ashwagandha is rich in iron.

Ashwagandha may possess immunomodulatory and anti- inflammatory effects.

Pregnancy & Breastfeeding

Ashwagandha is not recommended due to a lack of available scientific evidence. Ashwagandha may cause abortions.
